Electrically conductive contact pin

Abstract

The present invention relates to an electrically conductive contact pin provided with an elastic portion, wherein the elastic portion includes: a plurality of straight portions; and a plurality of curved portions connecting the straight portions adjacent to each other above and below, and further includes a slit portion for dividing the curved portions into split beam portions, a stopper for limiting an elastic deformation position, or a groove portion for forming a cut portion on the inner surface of the curved portions. The purpose of the present invention is to improve the inspection reliability of an inspection object and to prevent damage to the inspection object by facilitating elastic deformation.

         3 . The electrically conductive contact pin of  claim 1 , wherein beam widths of the split beam parts are larger in a direction from an inner part of each curved part to an outer part of each curved part. 
     
     
         4 . The electrically conductive contact pin of  claim 1 , wherein the slit part comprises a plurality of slit parts,
 wherein among the plurality of slit parts, a slit part provided at an inner part of each curved part has a larger available space width than a slit part provided in an outer part of each curved part.   
     
     
         5 . The electrically conductive contact pin of  claim 1 , wherein the split beam parts have radii of curvature that are larger in a direction from an inner part of each curved part to an outer part of each curved part. 
     
     
         6 . The electrically conductive contact pin of  claim 5 , wherein the sum of beam widths of the split beam parts is equal to the beam width of each of the straight parts. 
     
     
         7 . The electrically conductive contact pin of  claim 1 , wherein each of the split beam parts has a bent portion having curvature, and a beam width of the bent portion is smaller than a beam width of a surrounding portion. 
     
     
         8 . The electrically conductive contact pin of  claim 1 , wherein a beam width of each of the straight parts is less than a beam width of each of the curved parts. 
     
     
         9 . An electrically conductive contact pin comprising an elastic part, wherein the elastic part comprises:
